SPECIFICATION forming part of Letters Patent No. 604,011, dated May 17, 1898.. Application filed June 17, 1897. Serial No. 641,126- (No model.)

To a whom it may concern:

Be it known that I, JOHN A. ANDERSON, a citizen of the United States, residing in Wakefield, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Bicycles,of which the following is a specification.

This invention relates to that class of bicycles in which the pedals are applied to a lever which, by means of mechanism intermediate thereof and thedriving-shaft, operates the driving-wheel; and it consists of an improved speed mechanism between the pedals and driving-shaft and of improved mechanism for checking or applying brakes to the machinethrough the medium of the pedals.

The nature of the invention is fully described in detail below, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a sufiicient portion of a bicycle to illustrate my invention, a small portion of the frame being represented as broken out in order to better illustrate a part of the brake mechanism. Fig. 2 is an enlarged horizontal section taken through the hub of the rearor driving wheel. Fig. 3 is an enlarged vertical section taken through the hub of the rear wheel and driving mechanism thereon. Fig. 4: is an enlarged section in detail, taken on line 4:, Fig. 1.

Similar letters of reference indicate corresponding parts.

a, a, and I) represent portions of the frame, and 19 represents the rear or driving wheel, I) being the tire.

d is the driving-shaft, and A is the hub thereon, extendinginto the flange A (from which the spokes extend) and formed into the drum A. A sleeve B is loose on the hub A and is formed with the integral disk or flange B,'extending up to the drum A and constituting, with said drum and flange A, a case for the dogs C. These dogs are U-shaped and. extend around or embrace a ring D, to which they are pivotally secured by the pins O,which extend through said ring and both legs of the dogs. The dogs are bifurcated at O at their inner ends to embrace pivots D, and suitable springs 0 hold them normally from the inner side of the drum A. c are ordinary stop -pins. By this construction when power is applied, as below set forth, the

dogs act in concert, but do not when released drag on the rim or drum, thus saving friction. A suitable cord or ribbon e has one end secured to and coiled around the grooved portion of the extension B, formed on the part B, Fig. 2, while its opposite end is secured to the periphery ofa cam-wheel E, pivotally secured to the short arm F of the pedal-lever F, pivoted at f to the frame and provided with a pedal F; (A portion of the camwheel is represented as broken out.) I Rigidly secured to the inner surface of the cam-wheel E is a segment-gear H, which is in engagement with a segmentgear H, loose on the pivot f, by means of which the pedal-lever is secured to the frame. A link 9 has one end .secured at g loosely to the arm F and its other end at h or 71., asdesired, to the bar I, pivoted at I to the frame a. The other end of this bar is connected by a link I with the segment H. This construction is of course duplicated on the opposite side of the wheel. Pressing down the pedal F swings the lever F down and the short arm F rearward. This moves rearwardthe segment-gear H, and its engagement withthe gear H causes the former to rotate, and hence imparts rotation to the cam-wheel E, causing the band or ribbon e to mount its higher portion and impart accelerating rotationto the drum A, (through the medium of the clutching mechanism or dogs above described,) and hence to the hub A, thus speeding up the wheel. When the pedal is released from pressure, the case B is'returned to its original position by the spring J, which connects said case with the frame, as shown in Fig. 2. j

K is the brake-band, extending around the drum A" and having its opposite ends pivotally secured, respectively, at K and K to the downwardly-projecting arm L, and the rearwardly-projecting arm L" of the lever L pivoted at l to the frame a. A lever N is pivto the frame a.

An elbow-lever, Fig. 1, consisting of the long arm P and short arm P, is pivoted at P The long arm P is provided with a vertically-extending toe-piece m and with a rearward extension 0, which overlaps a horizontal pin 0, extending from the lever The short arm P is provided with a holder, Figs. 1 and 4, consisting of the side pieces'R and back piece R, the latter being convex in; cross-section in order to correspond with the periphery of the grooved rubber Wheel S,
